Ashu! Your friends at iCracked would love to help... reach out to me anytime man! Rachel, I feel it'd be nice to have a visual indicator as I touch the screen, right now if you can press anywhere and it just seems unresponsive. Also, for a while I didn't realize you could move obstacles so the "get a hint" constantly resetting the level was a little confusing. Finally, undo occasionally crashes the app. Overall, great work!
